CodeMirror VS terser

codemirror - a code editor component for the web

massCode uses Codemirror as the basis for the editor and .tmLanguage as the grammar for syntax highlighting. This tandem opens the door to over 600 existing grammars. The application currently supports more than 160 grammars. In addition to .tmLanguage, the application supports .tmTheme for themes. There is also…

After giving up countless times since I started this project, I finally managed to dig the dark secrets of Pyodide and run pyTermTk on a browser, all of this, of course, thanks to the magic of xterm.js. I know, my friend, I know what you are thinking, I was disgusted at first picturing that hideous javascript defiling the python purity of my code, but, when I saw my red pepper shining on webkit engine, well, I couldn't hold back a tear. And after that, who am I to not include also an editor and my collection of demos and examples? So, here it is, a super minimal buggy and feature incomplete pyTermTk Sandbox

syntax highlighting is simple with https://codemirror.net/

Can CodeMirror 2 be used to highlight code from a DIV or PRE tag (without the editor)?

There sure is, take a look at Code Mirror

Codemirror is open source, so you can look at, clone and experiment with its actual code as much as you like to figure out how it works.

Developed using the LAMP stack mainly because I'm more of a back-end (PHP) dev, and for various other reasons, like affordable web servers. The front-end is vanilla JavaScript (AJAX for dynamic stuff). I also use CodeMirror to provide the visual-code editor for programmers.

During my intial search i came across some outdated libraries like javascript-obfuscator and uglify-js(as if javascript code can get any uglier, am I right?). Then, I stumbled upon Terser, a modern library that supports ES6.

Example: You've got a main.js file that's as long as a Tolstoy novel. Fix: Use tools like UglifyJS or Terser to minify your code. They'll squeeze out all the unnecessary bits and give you a sleeker, faster-loading file.

They can do it, it is just turned off by default and require more advanced configuration.

Minifying is a common practice for optimizing production code. (for example, using Terser to minify and mangle JavaScript).

Minification: UglifyJS, Terser

Terser is JavaScript compressor that can minified specific method names.

Every release build of React Native uses terser to reduce the size of your JavaScript. And it operation can be omitted for Staging/Beta builds.

A minifier makes your code more compact so that it loads faster. Popular minifiers: Terser, swc.

There are many minifiers such as terser and uglify. But, because minifying also require to parse the JS, it is actually possible to use esbuild and SWC to minify the code. Here's a benchmark of the main minifiers.

This next one will help us reduce final bundle size by minifying the generated code. It's called rollup-plugin-terser and uses terser under the hood to minify the code.
